ERNST WEILER, OF BERLIN, GERMANY. VEHICLE-WHEEL RIM.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed March 7, 1905. Serial No, 248,833.

To all whom it may concern.-

- Be it known that I, ERNST WEILER, manufacturer, of Berlin, in theKingdom of Prussia, German Empire, have invented certain new and usefulImprovements in and Relating to Vehicle-Wheel Rims or Fellies, of whichthe following is a s ecification.

Wheel rims or fe lies consisting of a number of parts adapted to bescrewed together by means of continuous screw-threads are already known;likewise constructions in which the rim halves or members are adapted tobe assembled by means of oblique slots and pins or by means of ahelically-arranged bead or protuberance and with the hel of set-screws.These wheel-rims, however, ack the characteristic of the rim which formsthe subject of the present invention, which consists in the fact thatduring the assemblage of the rim members these latter, in addition to anautomatic centering, are only actually held upon the meeting of conicalor wedge shaped abutting edges.

The construction which forms the subject of this invention isillustrated in the accompanying drawings, in which Figure 1 shows aportion of the rim in front elevation with the edge removed. Fig. 2 is aside elevation. Fig. 3 is a side elevation, partly in section. Fig. 4 isa cross-section; and Figs. 5 to 15,inclusive, are views in cross-sectionof various modifications of the structure shown in the precedingfigures, showing only a portion of the felly and of the removabletire-securing rim in position thereon.

This construction is characterized by the fact that the two rim membersare provided with wedge-like ribs (1, either separate one from the otheror overlapping, so that after the application of the ring with thescrew-threads rotation through a very small angle is suflicientforobtaining a certain connection. In order to obtain during theattachment of the flange on the rim a mutual centering and thereupon arigid and secure connection between the two assembled rim members, theouter edge of the rim-periphery is chamfered so that only upon thefixing of the corrcspondingly-chamfered inner edge of the rim-flangewhich is to be attached is a completely-rigid assemblage produced. Theautomatic centering is further facilitated owing to the fact thatbetween the separate ribs a effecting the fixing a certain amount ofplay or space is left, which permits of relative displacement of the twoparts, if required, and also assists the firm assemblage of the.chamfered faces I) on the abutting edges.

The principle of the conical faces I) may be utilized in numerousconstructions. Figs. 4 to 15 show various arrangements of this kind. Itis not only a question of the form of the wedge-like ribs, but also ofthe centering and the joint between the rim nd the abutting edge formingthe detachab e IIIIlcrown. As shown in Figs. 14 and 15, by way ofexample, the rim edge may also advantageously be constructed in twoseparate parts, one of them being formed as a'smooth rim edge to bepassed over the rim, while the second part, which is crown-like andprovided with the ribs referred to, is intended in being united to therim to center the smooth rim edge which has been previously placed inposition and to press against the rubber tire. It will of course beunderstood that in the case of this separate crown-shaped part also allthe different wedge-rib forms and also the various formations ofitsabutting edge may be employed. By means of these oblique faces not onlyis an automatic centering obtained, but also a perfect joint between thetwo assembled rim members, which is the better insured if before theassemblage they are coated with a solid lubricant, which preventsmoisture, dust, and dirt from entering the rim. The perfect junctionmight also be obtained by forming on both the edges coming into contacta small groove serving for the reception of a packing-strip of somesuitable material.

Having explained the nature of my invention and described forms ofconstructing and the manner of using the same, what I claim, and desireto secure by Letters Patent, is

1. A wheel rim or felly in two parts, comprising a detachable ring orflange in which the ring and the outer edge of the rim carry helicallyformed ribs bearing mutilated screws engaging one with the other and atireengaging flange on each part by which the tire is wedged into andheld firmly in position when the parts are screwed together.

2. In a device of the class described, a dismountable outer wheel-rimcombined with an inner rim in which wedge ribs on each form a screwengagement so formed as to hook one within the other, so that they present conical pairs of wedge faces parallel with each other, by means ofwhich the centering and joint formation between the two assembled partsis simultaneously obtained, and a flange on the wheel-rim, and on theinner rim, between which the tire is held.

3. In a device of the class described, a Wheel felly or member having aflange on one side adapted to engage the securing edge of a rubber tire,a mutilated or non-continuous screw-thread formed upon the unflangededge of the felly, and an annular like threaded and flanged memberadapted to engage with the felly to secure the tire in place.

4. In a device of the class described, a Wheel felly or member having aflange on one side adapted to engage the securing edge of a rubber tire,a mutilated or non-continuous screw-thread formed u on the unflangededge of the telly, an annu ar like threaded and flanged member adaptedto engage with the telly to secure the tire in place, and apacking-gasket of elastic material interposed between the twoscrew-threaded parts.

5. In a device of the class described, a wheel-rim having a flange forsecuring one side of the elastic tire and an annular member with acoacting flange fitted to the wheelrim by means of a wedgingbayonet-joint.

6. In a device of the class described, a wheel-rim having a flange forsecuring one side of the elastic tire, and an annular mem-
